She can't take care of herself and she wants to go home, even if there is no one there to take care of her and she is difficult to get out of bed even to eat and it's been years since she has cooked or shopped for herself insisting she is able to do it but choose not to. What's troublesome is her habit of sleeping during the day only to start crying at 2 oçlock in the morning till around 9 if she stops at all, a couple of times she starts at 2 and by six at the evening she still keeps on crying and lamenting her terrible fate. She would stay bed and without getting up to eat or go to the bathroom; there is no reasoning with he: she says she wants to go home but when we agree she says we are leaving her alone to fend for herself when she is unable and sick, despite demanding being the one to demand going home. we've tried to keep her awake during the day and engage her in some activity but she refuses and if she is out of bed at all she only stares blankly into space or hops through channels often stopping at some foreign program she insist she understands and if she watches a program she often fails to follow the plot line. What's even worse is that in most cases she gets violent when we ask her to be quiter since it's late in the evening, she says she doesn't care about the time. She would start yelling how we should all die or how she will beat us or crack our heads open. she has hit my mother repeatedly and tried the same with me but I caught her hand and she started yelling that I was the one beating her. She yells non stop and the neighbours have complained on more than one occasion and the police has fined us. This is not a joke! If there is some advise you can offer on the situation it would be greatly appreciated.
